Hammers Patent
 

Hammermill with intersticed multilength hammers

A hammermill-type shredding apparatus having a rotor assembly disposed in a housing, the rotor assembly including hammer elements of longer and shorter lengths mounted in an intersticed or alternating manner thereon, a grate having thicker and thinner portions in like alternating manner so as to accept longer length hammers adjacent the thinner portions of the grate and between the thicker portions of the grate, the housing further provided with a comb assembly having finger portions extending into the circle defined by the hammers when in operation, and further extending between the hammer elements so as to remove and prevent any undesirable materials accumulations.

Hammermill having sealed hammers

A hammermill including a main shaft rotatable about a main axis passing longitudinally through the main shaft. Connected to the main shaft and spaced longitudinally along the main axis are a plurality of substantially parallel plates. Pivotally mounted between the plates along pivot axes parallel to and spaced from the main axis are a plurality of free swinging hammers for crushing material. A plurality of sealing members are positioned along the pivot axes and compressed between the hammers and the plates.

Wood pulverizer with improved hammers and anvils

An improved wood pulverizer is provided with a rotating disc studded with a plurality of curved tapered hammers. One or more anvils is secured to the pulverizer with the anvil having teeth and slots located adjacent the surface of the disc. The hammers of the rotating disc pass through the slots of the anvils as the disc rotates to tear and shard wood into bits and pieces for subsequent use or processing. The anvils of the present invention are formed with two or more useable surfaces so that the anvils can be removed, rotated, and replaced to present fresh cutting surfaces to the disc. Further, the anvils are formed by a series of bolted together anvil segments to allow replacement of only single segments in the event of damage.
